I know, I know, this isn't exactly what this product was intended for, but it's PERFECT for our needs! Our son has autism and ADHD and ALLLLLLL the energy and sensory needs that come along with them. And yes, we have a full size trampoline, but when weather isn't ideal for being outdoors, the indoor mini tramp and this plyobox are an absolute life saver! He is able to jump first thing in the morning before school and in the evening before bath and any time he needs a little jumping stimulation or energy release. The combo has been magical and his behavior is vastly improved since providing him with a little indoor jumping outlet that is safer than jumping off our piano into a pile of pillows like he used to do, or off of the stairs onto the trampoline. I love that the box has 3 different heights to choose from. It's extremely sturdy while being incredibly light weight, which is great because he can move it around on his own. The vinyl fabric of the zip cover is not only very grippy for our hardwood and porcelain tile floors, but it's easy to wipe clean when needed. It's also compact enough to be easily stored in a closet when we need it out of the way. I know we haven't used it as it was intended to be use, but I can tell you this; if it's sturdy enough for our boy who uses it for hours a day, it will work great for you to practice your box jumps in your home gym. I feel very secure letting him jump and climb and play all over it. Great product at a fair price! And yes, I paid full price for this!I sincerely hope this review has been helpful!
